Incorporating Sea to Summit's 2D PermaShell(TM) fabric and a premium 650+ Loft ULTRA-DRY Down(TM), the Trek bags are a refined classic. The 60/40 fill ratio in the Trek bags is maintained using a side block baffle and differential cut shell. In the top of the shell a 3D side wall, a feature normally reserved for technical alpine sleeping bags, provides more space for the down to loft right to the edge of the bag.For 2017, Sea to Summit has updated the Trek TKI with a new 3D hooded construction. Panels are stitched in a fashion to provide structural support to the hood and helps encase your head in colder weather. Static draft tube runs around the hood to maximize warmth around your face. the change to the new 3D hood from the previous flat hood reflects the move to a more technical end-user profile. Some bag weights and fill weights may vary by no more than 4 ounces
